Great question, actually... (Off-Topic)

Looking it up, it seems to work like this:

V-bucks (the game's premium currency) don't transfer between platforms unless they were earned through gameplay. Same for Battle Pass content. You can unlock stuff with your V-bucks on one platform, and unlocked content does carry over freely, but you don't make progress for the unlocks across different platforms. You do get a notification telling you how many V-bucks you have on another platform, but there is no way to transfer it., and any bonuses that the Battle Pass gives you (XP boosts or whatever) are unavailable unless you play on the platform that you bought them on.

In Destiny terms, Eververse content acquired with Silver or Silver Dust would transfer, but none of your silver or Silver-obtained dust would. On top of that, the content would not be knocked out on your Prismatic Facet, so you'd have to fill out that "progress bar" separately.

Slightly annoying, but understandable. It would mean that a lot of your Silver would go to waste on the new platform by rewarding you with content that you already had (which would be increasingly annoying as they add new content to the Bright Engram pool), but it's a fair trade, I feel.
